Pentium Gold G6405 Details

Built on Intel's Comet Lake architecture and manufactured on a 14 nm process, the Pentium Gold G6405 is a mainstream desktop processor launched in March 2021. While it is now over three years old, it remains a viable option for basic computing tasks due to its integrated graphics and modest performance. Designed for the Socket 1200 platform, the G6405 is compatible with Intel's 400 and 500 Series chipsets, offering flexibility for entry-level builds. The processor features a dual-core design with four threads enabled via Intel Hyper-Threading, allowing it to handle light multitasking and productivity workloads more efficiently than a traditional dual-core CPU.

Operating at a base clock of 4.1 GHz with a locked multiplier, the G6405 delivers strong single-threaded performance for its class. It includes 4 MB of L3 cache, 0.061 MiB of L1 cache, and 0.244 MiB of L2 cache, supporting fast data access during common operations. The processor supports DDR4 memory at up to 2666 MT/s in dual-channel mode, providing a memory bandwidth of 42.7 GB/s. Connectivity is handled via PCIe 3.0 with 16 lanes directly from the CPU, and it features Intel UHD Graphics 610, which includes 24 execution units and a maximum frequency of 1.15 GHz, supporting up to three displays.

In terms of power efficiency, the G6405 has a TDP of 58 W, making it suitable for compact and energy-conscious systems. It supports a range of Intel technologies, including virtualization features like VT-x and VT-d, as well as instruction sets such as AVX2, SSE4.2, and AES-NI. The processor also supports hardware virtualization and IOMMU for direct hardware access in virtual environments, enhancing its utility in light virtualization scenarios.

Benchmark data reveals that the Pentium Gold G6405 achieves a single-core score of 4920, ranking it #995 among 2060 CPUs, and a multicore score of 4510, placing it #1207 of 2060. Its overall score of 4756 ranks it #1060 of 2060, indicating that it holds a competitive position in the lower end of the desktop CPU market. While it trails behind modern high-end processors, it performs on par with mid-tier CPUs from the early 2010s, such as the Core i5-3360M and the Xeon E5-2650 v4. In the top 50 rankings, the G6405 falls well below processors like the Core Ultra 9 285K and the Ryzen 9 9950X3D, which dominate the performance charts.

As of March 2026, the Pentium Gold G6405 is best suited for basic office use, web browsing, and light multimedia consumption. Its integrated graphics eliminate the need for a discrete GPU in entry-level systems, while its 65 W TDP and socket compatibility make it a cost-effective upgrade option for older systems. While it lacks the power of modern multi-core processors, it remains a practical choice for users who prioritize affordability and efficiency over raw performance.
